GENERAL DESCRIPTION

The AD5450/AD5451/AD5452/AD5453 are CMOS 8,

10, 12 and 14-bit Current Output digital-to-analog

converters respectively.

These devices operate from a +2.5 V to 5.5 V power sup-

ply, making them suited to battery powered applications

and many other applications.

These DACs utilize double buffered 3-wire serial interface

that is compatible with SPI

and most DSP interface standards.

On power-up, the internal shift register and latches are

filled with zeros and the DAC output is at zero scale.

As a result of manufacture on a CMOS sub micron

process, they offer excellent four quadrant multiplication

characteristics, with large signal multiplying bandwidths

of 10MHz.
